Unable to display enclosure name under the enclosure in VEA for array FUJITSU ETERNUS4000

Customer has installed SFWHA6.0.1 on Windows2008 R2 Standard version.It has only one array E4000. MPIO looks fine.Harddisk1 and Harddisk2 appear within the default enclosure which is displayed as Disks@Hostname.

Who knows the meaning of err 1005 within vdid_get() failed err(1005) according to vxisis.log. Any comments are really appreciated!
